INTUS Windows

INTUS Windows INTUS unites extreme energy efficiency with affordability and versatility. INTUS means ‘within’ or ‘inside’ in Latin.

We create high performing windows and doors that conserve energy, increase thermal performance, and reduce noise. Since 2010, INTUS Windows has been a pioneer in manufacturing and distributing extremely energy efficient windows and doors in the United States. Our windows have been essential components in the U.S.’ first Passive House Certified church, the first LEED-Platinum mixed-use residential/

retail building, Maine’s first Passive House school, NY’s largest Passive House co-housing project, and dozens of LEED, Passive House, and Energy Star Certified building projects. From our products to our team, we are innovative and diverse. The INTUS team is made up of over 14 nationalities with the majority being bilingual. Our team includes engineers, drafters, project coordinators, estimators, technicians, business developers, and supporting staff in consulting, accounting, marketing, graphic design, administration, and more, to ensure that our clients receive the service they need and deserve. Our main office is right outside Washington, D.C. in Fairfax, V.A., and we service the entire United States, with offices in New York City, Boston, Philadelphia, and Baltimore. By 2036 we aim to offset carbon emissions enough to recover the absorption rate of 5 billion trees through our energy efficient products!

Urban projects are facing increasing pressure to improve occupant comfort—not just energy performance.

Noise from traffic, transit, and dense city environments can directly impact how people experience residential, hospitality, and mixed-use buildings.

That’s why acoustic performance is becoming a more important part of envelope design discussions early in the project lifecycle.

In our latest article, we explore how window system selection and envelope performance contribute to better acoustic comfort in urban buildings.

Building codes are placing increasing emphasis on airtightness—and for good reason.

Excessive air leakage can impact energy use, thermal performance, occupant comfort, and moisture management. That's why airtightness is becoming a bigger part of both compliance discussions and overall building performance strategies.

For architects and sustainability consultants, this means air leakage can no longer be treated as a detail to resolve later. The decisions that influence airtightness often happen much earlier through envelope design, detailing, and coordination.

Projects that address airtightness early are often better positioned to meet both performance goals and compliance requirements.

Choosing the right façade system is rarely just a design decision.

Different projects require different priorities—whether that’s larger glazing areas, structural performance, thermal efficiency, constructability, or long-term operational value.

Aluminum systems are often selected for projects with larger openings and commercial façade requirements, but the right choice ultimately depends on the building’s performance goals and how the envelope is expected to function long-term.

Modern building projects require more coordination, more performance knowledge, and more collaboration than ever before.

That’s why our Lunch & Learn sessions focus on practical project challenges.

INTUS offers private AIA-accredited sessions covering topics like:
• High-performance façade systems
• Unitized curtain walls
• Passive House design strategies
• Envelope coordination
• System selection and constructability

Each session is tailored to the specific interests and challenges of your team.

Window design decisions rarely happen only once.

Teams test different systems, revise configurations, adjust layouts, and coordinate performance requirements throughout the design process. The challenge is doing all of that efficiently without slowing projects down.

That’s where BIM tools become valuable.

Better digital coordination helps architects move through window design decisions faster, reduce revisions later, and keep teams aligned as projects evolve.

A lot of project delays don’t start on-site🚫

They start much earlier—with disconnected information, misaligned coordination, and teams working from different assumptions. As projects become more complex, coordination is becoming just as important as the products themselves.

That’s why more teams are adopting technology-driven workflows to improve visibility, reduce friction, and keep project information aligned from design through delivery.

Because better coordination doesn’t just save time, but helps avoid costly mistakes later in the project lifecycle.

The demand for larger glazing isn’t slowing down. But the bigger the opening, the harder it becomes to balance aesthetics, performance, and real-world constructability at the same time.

That’s the challenge many project teams are facing today.

Because expansive glass only works when the façade system behind it can support long-term building performance—not just the visual concept.

A lot of “net-zero” conversations still focus on what gets added to buildings later:

Solar. Mechanical systems. Smart technologies.

But many long-term performance problems are created much earlier—during envelope design.

The reality is:
you can’t compensate for poor envelope performance with more equipment forever.

As energy standards continue evolving, architects and sustainability consultants are under increasing pressure to think beyond isolated systems and toward total building performance from the start.

That shift is changing how teams approach façade coordination, detailing, and specification decisions much earlier in the project lifecycle.

New York City’s building regulations are continuing to push the industry toward higher-performing, lower-emission buildings—and Local Law 97 is part of that shift.

For architects and developers, this means building performance can no longer be treated as a late-stage consideration. Decisions around the building envelope, glazing, and airtightness increasingly impact long-term energy efficiency, operational costs, and compliance readiness.

As standards evolve, project teams are under greater pressure to:
• Reduce operational energy demand
• Improve envelope performance
• Future-proof building assets
• Deliver measurable performance outcomes

At INTUS, we support architects and developers with high-performance window systems engineered for modern building envelopes—helping teams integrate performance into the design process with greater precision and confidence.
